iphone - Where is NSAlert.h in the iOS SDK?

Question

According to iOS's Using and Creating Error Objects, one can display a error object with the following code.

NSError *theError = nil;
BOOL success = [myDoc writeToURL:[self docURL] ofType:@"html" error:&theError];

if (success == NO) {
    // Maybe try to determine cause of error and recover first.
    NSAlert *theAlert = [NSAlert alertWithError:theError];
    [theAlert runModal]; // Ignore return value.
}

Unfortunately, I am not smart enough to figure out how to include NSAlert.h.

Any help would be appreciated.

That document is referring to the (OS X) AppKit framework. Right after that box, it says:

(UIAlertView, the UIKit class corresponding to NSAlert, has no equivalent method for alertWithError:.)

You can still use UIAlertView, but you'll need to manually populate the title, message, and button strings from the error.
